Its colder than hell, 31* according to my weather station, so I took the 20 out front and put a few rounds through it.
Wolf steel case, 31*, 20 group buy barrel
2600 FPS, SD 25fps
Wolf steel, 50*, 20 group buy barrel
2622 FPS, SD 20.5fps
Itll be near 80* by Thursday so Ill get some more data then.
Have to love western Oklahoma weather lol.
Edit: hell if it stays in the 1 FPS/degree range its better than A2520.
biodsl Wrote:I only have one small data set on this. It was a Moscow Match load of 29.3 grains of stock Wolf steel case powder under a 107SMK. Out of a 22" BHW barrel.
At 46 degrees the average velocity was 2716 fps. At 80 degrees it was 2744
A small sampling, but those numbers are encouraging. I really want to work up a 129 ABLR load for my 12" GB
